    摘要： A liquid purge valve comprising a housing for sealingly fitting at an uppermost end of a substantially vertical pipe, an outlet tube extending from the housing and projecting into the pipe, an outlet port fitted with a sealing boundary and sealable by a sealing member pivotally secured within the housing so as to pivotally displace between a closed and an open position, a biasing member biasing the sealing member into its open position, and a mass articulated to the sealing member and extending downwards into the pipe. The mass applies a force at an opposite direction of the biasing member such that the resultant force acting on the sealing member determines its position such that when water level rises within the pipe the sealing member displaces into the open position.

    摘要： A liquid level control apparatus for a flush tank includes a valve mechanism communicating with a fill tube and operable between open and closed conditions, two floats, at least one of which is coupled to the valve mechanism for closing it when the at least one float reaches a predetermined height, and structure interconnecting the floats so as to substantially prevent their vertical movement until a predetermined liquid level is reached corresponding to the predetermined height, thereby causing sudden movement of the at least one float to the predetermined height and sudden closing of the valve.

    摘要： A float operated valve for controlling the rate of flow of water from a pipe carrying water under pressure, to a vessel, comprises a pipe having an end opening of selected diameter and a flange of larger diameter surrounding the pipe. A flexible diaphragm is attached over the flange having a central closure pad adapted to cut off water flow when pressed against the pipe. A small orifice is drilled through the diaphragm so that when the flow is shut off, water can still flow through the orifice to the second side of the diaphragm. A second short pipe having a similar flange is bolted against the diaphragm to the first flange, to provide a water tight seal. There is a second small orifice in the second end of the second pipe, and a float mechanism is provided with a closure tip to close the second orifice when the water level is at a selected value. The closure tip varies the size of the second orifice so that the orifice is responsive to the float. Depending on the ratio of areas of the first and second orifices, water pressure on the second side of the diaphragm prevents flow. When the second orifice reaches a selected ares the diaphragm no longer seals the first pipe and a high flow of water is provided. A removable, resilient insert in the first pipe seats the diaphragm. The resilient insert minimizes valve maintenance while prolonging component service life. An anti-syphon relief prevents reverse fluid flow during vacuum or negative pressure conditions. The relief causes air to enter the valve to break the suction created by the vacuum or negative pressure condition while preventing water loss during normal operations.

    摘要： A fill valve for a water storage tank includes a riser assembly, a valve housing mounted on an upper end of the riser assembly, and a pilot operated diaphragm valve mounted in the valve housing. A float housing is connected to the valve housing. A combination float and float arm has a first end pivotally connected to a valve housing cap for opening and closing a pilot orifice in the valve housing cap. A second end of the float arm is connected to the float. The float is located in the float housing which has an inlet opening for allowing water to spill into the float housing so that the float rises upwardly and the first end of the float arm fully seals off the pilot orifice. The first end of the float arm has a central arm and a pair of flexible pivot arms that are laterally displaceable for engaging a pair of spaced apart fixed pivot pins on the valve housing cap.

    摘要： A ballcock is constructed with upper and lower housing members which are joined by a bayonet-type fitting. The juncture of the upper and lower members defines a valve chamber which sits atop the orifice of a vertical inflow tube carrying water from below the lower housing member. A valve in the valve chamber controls the flow of water out of the orifice. The valve includes separate, spaced upper and lower resilient valving members that provide a pressure chamber. Pressure in the chamber is controlled by a spherical-head metering pin passing through apertures in the upper and lower members. A slip-on silencer telescopes over the orifice and defines, with the exterior of the inflow tube, a quieting passage. The quieting passage has an annular intake at the top and terminates below in a pair of downward directed nozzles. The spherical-head metering pin makes a ball-and-socket connection with a lever. The lever is resiliently connected to the upper housing member and operated by a metal rod connected to a float.

    摘要： A ballcock assembly having an upright standpipe for delivery of flush water, a control valve assembly at the upper end of the standpipe, and a float and ballast assembly slidably mounted for up and down movement relative to the standpipe and connected to the control valve assembly. The control valve assembly operates to open the valve to flow of flush water from the standpipe assembly in response to downward movement of the float and ballast assembly. When the float assembly is caused to rise by incoming flush water from the standpipe, it ultimately causes the control valve to shut off incoming flow of flush water from the standpipe.
